The Alter function

The following code shows how the Alter function renders the Home template by invoking the ExecuteTemplate method with the writer and customers arrays as parameters:

// Alter - execute template
func Alter(writer http.ResponseWriter, request *http.Request) {

    var customer Customer
    var customerId int
    var customerIdStr string
    customerIdStr = request.FormValue("id")
    fmt.Sscanf(customerIdStr, "%d", &customerId)
    customer.CustomerId = customerId
    customer.CustomerName = request.FormValue("customername")
    customer.SSN = request.FormValue("ssn")
    UpdateCustomer(customer)
    var customers []Customer
    customers = GetCustomers()
    template_html.ExecuteTemplate(writer,"Home",customers)

}
